I'd pull the plug out and check out the color to make sure you are not running to lean. You might also want to spray some wd-40 around the manifold where it mounts to the cylinder and where the carb mounts to the manifold while it's running to see if you have any vacuum leaks. If the RPM changes you most likely have a vacuum leak and the motor could be running lean.
